`Aingvlicatio'n filed lfovember 1i 1924.k Serial No. 747,205.

This invention relates to wall molds that ymay beadvantageously used tor the forma- '.tion of Aconcrete walls or walls made of any plastic materiaLthe wallmolds being de-A jectmatter of a companion application tiled v The primary objectof provide a seriesot panel mol dinembers that maybe easily andquickly assembled or.k biiilt up to form a stro-ng and rigid structure into which concrete or other plastic material may be poured-or otherwise deposited, tamped or otherwise packed, and safely held until the concreteor plast-icwall has set or cured at Whichtime the panel mold members may beV 20 readily removed and again used.

Y Associated with these panel mold members are cor'- ner or angular members which permit of the Y moldmembers being used in the formation ofY angular walls. y Y

Another object o'l` this invention is to pro'- vide knovel collapsible joists or kgirdei cores for producinghoists or girder recesses in a molded wall and into whichV recesses the ends of the ,ioists or. girdersmaybe placed after aw'all is completed. f .Y Y A further objecty of this invention is to' providera form that may be mounted-iii wall openings tor theformation of ,-lintels, sills, rails or other door and window ftrame mem- ,HS' bei'sl, As fa matter of fact' A`the lopening ,tormsmaybe used in the preduction otrany kind of ornamentationy to anopening.

To put my invention into practice, l nee multiplicityot panel mold members in the 'formation of ai` hollow concrete wall oit' eX- tensive dimensions and each panel mold member is preferably of such size that-itcan be conveniently handled by workmen and any part of the mold members rapidly assembled fora wall of desired dimensions.

Each' mold Vmember comprises a mold board Yl' provided with a traine 2 lhaving webs 3 suitably connected to the mold board and to the trame so thatthere is a rigid panel-like mold member. The member is preferably made of woodand to strengthen and reinforce the same the frame. 2 is provided'with a. metallic'binder strip l having a flange embedded in the mold board l and flush with the .face of said board. The f metallic `binder strip 4 may be secured to the frame 2 by any'suitable 'fastening means and with the'framemadelotwood it is `protected to a .'The panel moldY members are adapted to Vbeplaced edge to edge Tor oiietupon another Vand with'saidv mold members .in `abutting .be formed which *necessitates lacing the vrpanel moldmembers at an angle relativeto oneV another, I use outer coupling members V7 and inner coupling members 8, the outer coupling membersrbeing in the form ot angle bars placed inthe angle formed by thel ends. of two Ymold members and connected thereto by the clips 6, asbest shown in'Figs. l and 2. These same ligures show the inner coupling'meinbers asy being in the formy of angle barsy provided with flanges 9 that-facilitate installing the clips 6 in connecting mold members to the coupling memf bers. `These inner coupling members may have bottom iianges or feet l0 and the inner oi outer coupling members may be placed in superposedrelationshonld the height of a wall necessitate more than one inner or outerl coupling inemberat a corner.

or form i3 may be n'niinntedin the openingr l2 `clips '14 which and retained therein by side and end channel the inner side ot' ihe Wall 1l andthe outer nside of *the iframe or form 13, The iframe or forni 13 Vhas its upper and lower ends shapedto receive `concrete for the formation of a {lintel l' and a `sill V16, lwhile the sides oiE the iE ame or `forni `formed first, then i concrete poured into `the sides of `*the iframe or iorm to `produce the rails I7 andthen the lintel l5 formed. Should theconcrete wall lil be `of lhollow construction the top of saidV `wall inlay be closed by using'the nsnal tar paper and a metallic screen 18 iorisupporting.;r a concrete capor closure 1i9 on-the Wall To providcclearance for the ends of joists, girdersbeams or other Iloor orroo'fsnstaining members, I employ collapsible cores `which may be temporarily secured to 'laces of thekpanelanold members. `llach core co1nprises a back plate 20, a long channel menr ber 21, end channel members Q2, andan intermediate channel member Q3. The back plate 20 extends through the long channel member 21 andthe `end channel members are placed on the ends oi the long; channel member lfto retain the plaie El) against the back of the long channelmeinber 21, and She channel member 23 is `fixedin the long: channel member 2l as a spacer against the Walls of the channel member 21 opposite the ends of the channelmembersQQ. The backplate Q0 `is adapted to be securednto a ymold inem .ber Lto hold `the ,collapsible .core .in :position 'for the formation of a recess or o ening 24: in the inner utaceoftheconcrete Wa 1. After the Wall has been formed the back plate 20 "may be Withdrawn and the collapsible core removed. l the concrete Wall is oi` hollow `constructienathe removal oi' the core is facilibocliments of 1n f invention it.isitofbefunder-"` stood ythat the `structural 4elements are .susceptible `to such variations and modifications as 4fill :within the scope ofithe appended claims. i
